Here's a great idea for you. Why don't you camp out and snag a seller as they approach the coin store. I hear some coin shops are only paying the last bullion price for silver coins and there won't be a tax for you to pay.
I've heard some horror stories here in northern California of what dealers are paying the public for their silver coins. You might be able to pick up some real cheap morgan ot peace dollars.
Goof luck!
